http-compression

问题 I have heard a lot that one should use gZip for their webpages for faster access and downloads, and that it also saves the bandwidth. So what is this gZip compression and how does it make the downloads faster ? Does it compress the HTML and images or just the HTML. If I am to start using gZip in my webapps what considerations do I need to make ? Are there any server or browser restrictions for it, or does it support a particular encoding only. 回答1: GZip is a form of data compression -- ie it

问题 I am having issues with javascript files not decompressing in IIS7 and stylesheets not loading properly. I can fix this issue by turning off Static compression in IIS but this can't be a permanent solution. The issue has suddenly started happening. We haven't changed the code. The web application is an asp.net web forms app in .net 4. static and dynamic compression was set in IIS. another web forms web application is still running fine with static compression set at the application level. the

问题 What is the best plugin for Rails that gzips my webpage output? Edit: The company I am hosting with has stated they will not install mod_deflate . 回答1: Unless you are running your Rails application without another webserver (which usually isn't a great idea), you should probably look at your webserver. All major webservers have options to enable gzip. For example, for Apache, you can use mod_deflate. 回答2: Have you tested to see if it's already enabled? If your hosting provider uses Apache it

问题 I was using WebPageTest to test the performance of my Azure Web App (ASP.Net vNext Web API/Angular). I got an F for both "Compress Transfer" and "Cache Static Content". After searching StackOverflow and Google, I added the following to my web.config: <urlCompression doStaticCompression="true" doDynamicCompression="true" /> <httpCompression> <dynamicTypes> <clear /> <remove mimeType="*/*" /> <add enabled="true" mimeType="text/*"/> <add enabled="true" mimeType="message/*"/> <add enabled="true"

问题 I am currently working on migrating few of my MVC3 Controllers to MVC4 Api Controllers. I have implemented Compression mechanism for MVC3 controller Get Method Responses by inherting ActionFilterAttribute and overriding OnActionExecutiong method. After some Research I found that I need to use ActionFilterMethod from System.Web.HttpFilters . It would be great if somebody can share piece of sample code to get me started for this compressing HTTP response using GZip 回答1: The easiest is to enable

问题 I am using GZIP compression technique to compress various files in my application. All the files were getting Gzipped and compressed when I was using them on my local server (jBoss EAP 6.1--Standalone-Full profile) but when I tried to implement that on my server (Linux System) the same is not happening . I added this in my standalone -- > for windows system . <system-properties> <property name="org.apache.coyote.http11.Http11Protocol.COMPRESSION" value="on"/> <property name="org.apache.coyote

问题 I have a c# client talking to a cherrypy(http/rest) webservice. The problem is i can't both turn on compression and caching at the same time. request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate; By leaving out the above line I get the correct caching headers (If-None-Math,If-Modified-Since) while commenting it out gets me the compression headers (Accept-Encodig:gzip) but not the caching headers. It seems to me like a bug but maybe i'm doing something

问题 My Grails 1.3.7 controller is generating some JSON & I would like to send it to the client in compressed (zipped) form, as the amount of JSON can be 2+MB uncompressed. The resources plugin I found seems to compress static resources only. Is there a way to compress dynamic controller output as well? 回答1: I guess you would need the below configuration in Config.groovy if Ui-Performance plugin is used: uiperformance.html.includeContentTypes = ['text/json','application/json'] Also have a look a

问题 I wrote a piece of Rack Middleware to automatically unzip compressed request bodies. The code seems to be working just fine, but when I plug it into my rails app, I get a failure "Invalid JSON" from ActionController::ParamsParser. As a debugging mechanism, I'm writing both the zipped content, and the unzipped content to a file (to make sure that code is working properly) and I do receive my original JSON document (before the client zips it up). The data I'm posting is JSON data, and the

问题 I have trouble setting up the compressing in IIS 7.5. In the "%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" folder there are my files gzipped, but the browser recieves the original files. Even after refreshing the page again and again with Ctrl + F5. Also, I tested this in Chrome, FF and IE (no "Content-Encoding: gzip"-header). The browser is sending the "Accept-Encoding:gzip, deflate, sdch"-header. Can someone give me a hint? Here is what i've done so far: 1) Changed the
